Posts tagged: MD5 Password Cracker

BozoCrack is a depressingly effective MD5 password hash cracker with almost zero CPU/GPU load. Instead of rainbow tables, dictionaries, or brute force, BozoCrack simply finds the plaintext password. Specifically, it googles the MD5 hash and hopes the plaintext appears somewhere on the first page of results.

It works way better than it ever should.

How?
Basic usage:

$ ruby bozocrack.rb my_md5_hashes.txt

The input file has no specified format. BozoCrack automatically picks up strings that look like MD5 hashes. A single line shouldn’t contain more than one hash.
